The production of meat from animal muscle cells in a bioreactor is a promising way of securing the supply of protein-rich food for the world's growing population without harming the environment and climate. The first cell-based meat products have already been authorised in Singapore and the USA. What is possible on earth could also enrich space missions. This is shown by initial investigations by two independent research teams from the European Space Agency (ESA) in Germany and the UK, who have tested the cultivation of cultured meat in space.

Whether for dyeing and waterproofing clothing or for producing fibres, the textile industry still uses fossil raw materials and chemicals that are harmful to both people and the environment. With a view to sustainability and resource efficiency, however, sustainable solutions are entering the market. Products made from recycled polyester fibres, waste materials from the food industry, high-tech fibres made from biotechnologically produced spider silk or dyes made from algae are just a few innovative examples.

The figures speak for themselves: In 2022, Germany was by far the largest sales market for protein foods produced without animals, at 1.9 billion euros. Germans, who are otherwise sceptical about food innovations, are open to dairy products, fish and cheese produced using optimised microorganisms and cell-based processes. According to recent surveys, a good 60% of over-25s and almost 80% of under-25s would at least like to try them.

Insects have long been part of the diet in many countries. They are not only rich in proteins, minerals and vitamins. They are also relatively easy to keep and produce significantly fewer greenhouse gases than pigs or cattle.

It may not have been enough for the Grand Prize, but four of the 19 German teams had a special reason to celebrate at this year's final of the iGEM Jamboree in Paris last week: at the most important global competition fo

It is the annual mega-event for synthetic biology: for the 20th time, thousands of young researchers, start-ups, investors, politicians and journalists from all over the world will come together from 2 to 5 November for the Grand Jamboree of the iGEM 2023 competition. This year, around 400 university teams will be competing in Paris for gold, silver and bronze medals as well as numerous other awards, including 19 German teams (see below).

As part of its bioeconomy research funding programme, the Federal Ministry of Education and Research (BMBF) aims to combine biotechnology with other promising future fields. These include artificial intelligence, robotics, nanotechnology, computer science and engineering. This is because innovations and disruptive developments are increasingly emerging at the boundaries between disciplines.

Whether dowels, egg spoons or armature boards: plastics are omnipresent. Because the mostly petroleum-based materials are light, durable and versatile in industry. At the same time, their production from fossil raw materials often releases large quantities of the climate-damaging greenhouse gas CO₂. Experts therefore see great potential in the use of bio-based plastics in lightweight construction to reduce CO₂ emissions in industry.

The Federal Ministry of Education and Research (BMBF) is investing around 50 million euros in innovative plant breeding research that is open to technology and methods as part of a new funding measure. The aim is to be able to guarantee a reliable, climate-resistant supply of high-quality, healthy and safe food.

For numerous species of living organisms, the climate crisis will lead to environmental conditions that they will not be able to survive. Microalgae could fare differently, as a study by GEOMAR Helmholtz Centre for Ocean Research Kiel, the University of Würzburg and the University of East Anglia (UEA) has now shown. According to the study, the unicellular organisms can adapt to nutrient deficiencies, such as those to be expected in warming seas, with the help of a light-driven proton pump.
